FAQ

Frequently asked questions

Briefly about industry tasks, quotes and drawing formats. Other questions — in the FAQ block on the home page.
What metal do you make flue ducts and air ducts from?
From 1–10 mm plate, not only carbon steel. We make both thin air ducts, for example from 2 mm plate, and heavy-wall flue ducts up to DN 2000 with flanges, bends and transitions.
How do I get a cost estimate and how much does it cost?
The estimate is free. Send your drawing and a description of the task through the form on the site, via WhatsApp or to info@kztm.kz — an engineer will prepare a commercial offer with exact pricing and lead times from 24 hours on business days.
What formats do you accept drawings in?
2D drawings: DWG, DXF, PDF, as well as native CAD formats — IDW (Autodesk Inventor), CDW/FRW/SPW (KOMPAS-3D), SLDDRW (SolidWorks), DRW (CATIA). 3D models: STEP (.step, .stp), IGES (.iges, .igs), Parasolid (.x_t, .x_b), SAT (ACIS), as well as native ones — IPT/IAM (Inventor), SLDPRT/SLDASM (SolidWorks), CATPart/CATProduct (CATIA), m3d/a3d (KOMPAS-3D), PRT (NX, Creo). If you only have a paper sketch or a sample part, our design engineers will prepare the working drawing themselves.
